Light

With its incredible strength, chemical stability, high thermal conductivity and low electrical resistance, it's no wonder that graphene is finding more and more uses. Soon, however, it may be facing some competition from molybdenum di-sulphide – a thin metallic film that can emit light. Read More
Scientists have been observing the wave-particle duality of light for centuries, but never has light been seen to behave like matter. Until now, that is. Researchers at Princeton University have devised a method for giving light the properties of liquids and solids, with huge potential ramifications in the study of quantum mechanics and other areas of physics.

A new prototype light detector uses graphene's light-absorbing properties to see in a broad band of light wavelengths that includes terahertz waves. These fall between the microwave and infrared bands, thereby making it possible to look just beneath the surface of opaque objects such as skin and plastic. Read More
Researchers at Rice University's Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras. Read More
We've seen a plethora of accessories for the GoPro Hero actioncam cropping up over the past few years, including everything from stabilizers to drones to helmet-mounted poles. Surprisingly, though, except for scuba-specific models, there's been almost nothing in the way of lights. Australian bike gadget manufacturer Knog recently set out to fill that void, by releasing its Qudos Action light earlier this month. I recently had a chance to get my hands on the thing, and liked what it had to offer. Read More
Efficient as fiber optic cables are at transmitting data in the form of light pulses, they do need to be physically supported, and they can only handle a finite amount of power. Still, what's the alternative ... just send those focused pulses through the air? Actually, that's just what scientists at the University of Maryland have already demonstrated in their lab. Read More
Since being introduced in 1998, over 1.5 million of the smart fortwo city cars have been produced. The company has now revealed the third-generation, with the new fortwo and forfour models boasting a colorful new design, a range of modern engines and turning circles tight enough to take on the narrowest city streets.

Light might be the preferred option for transmitting data over long distances via cables, but when it comes to short range wireless, radio waves rule in the form of Wi-Fi and Bluetooth. Now Mexican company Sisoft, working with researchers from the Autonomous Technological Institute of Mexico (ITAM), has developed a wireless technology that transmits data in visible light emitted from LED lamps, while lighting the room at the same time.

In a conventional camera lens, the iris consists of a set of overlapping mechanical blades that control the amount of light entering the camera. As efficient as this mechanical system is, it is too bulky and too difficult to miniaturize to be incorporated in smartphones and other compact devices. To address this, a team of researchers has used "smart glass" to create a micro-sized electronic iris that may bring much greater image quality and flexibility to smartphone cameras. Read More
A new scientific instrument for detecting and observing remote exoplanets has been successfully installed on Unit 3 of the ESO's Very Large Telescope (VLT). The Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, or SPHERE, recently returned its first set of images and is promised to revolutionize the exploration and study of these distant celestial bodies.
